Is it possible to submit a form via email as a whole PDF but rename the PDF attachment in the process? I am using Acrobat X. I would like to set the PDF file name attachment to the value of a form field.

Yes, I have access but the local machine of every user is a mobile device (specifically an iPad). So I don't think that's possible. So this cannot be done via JavaScript when a button is pressed before the submit operation takes place? The iPad app does allow the execution of JavaScript in the PDF.
